Title: Device for the heat insulation of roof surfaces
Inventor: VOELKER HEINO DIPL PHYS
IPC: E04D13/16
Filed: 1981-07-16
Abstract: A heat insulation, located outside the outer surface (4) of roof rafters (1), having heat-insulating material (14), in particular in the form of a lightweight mineral-fibre felt, is produced in that the supporting structure (batten arrangement 2) for the roof covering is arranged at a distance from the outer surface (4) of the roof rafters (1) via separate spacer elements (6), which are subjected to pressure and are supported on the outer surface (4) of the roof rafters (1), and the resulting space is filled with the heat-insulating material (14). Errors in alignment between the outer surfaces (4) of the roof rafters (1) can be aligned in that each spacer element (6) has a lower base part (7) and an upper supporting part (8) which can be locked with respect to one another in different vertical positions, for which purpose the supporting part (8) can be fastened on the base part (7) by cotter pins (23) which engage through selected vernier bores (19a, 19b, 20a, 20b, 21a, 21b, 22a, 22b). The base parts (7) can be fastened, by a lower bottom surface (10), on the outer surfaces (4) of the roof rafters (1) via nails or rapid-fixing screws (12), if appropriate with the interposition of a trussing sheet (13) as vapour barrier, on which outer surfaces of the roof rafters the mineral-fibre felt forming the heat-insulating material (14) is applied with full surface contact. The upper supporting parts (8) are then fastened, through the mineral-fibre felt, in the desired vertical position on the base parts (7) and, if the supporting surfaces (9) of said supporting parts do not form the supporting structure for the roof covering, a roof-batten arrangement (2) is fastened thereon by rapid-fixing screws (11), it being possible to use conventional roof battens (3) by anchoring the batten arrangement (2) in the supporting surfaces (9) of the supporting parts (8). <IMAGE>

Title: Method and device for determining the flow behaviour of biological liquids
Inventor: MYRENNE HEINZ
IPC: G01N33/487
Filed: 1981-09-28
Abstract: In a method for determining the flow behaviour of biological liquids, in particular erythrocyte suspensions, the liquid is passed through a flow resistor, for example a filter, inside a system of communicating tubes. This avoids interfering effects due to drop formation at the drainage end of the measuring system and makes measurements possible at extremely low pressures. The filter (5) representing the flow resistor is preferably fitted inside the rising limb (3, 4) of the communicating tubes and the amount of liquid flowing through the filter is also measured in the rising limb of the communicating tubes. <IMAGE>

Title: Fuel feed unit
Inventor: KRAEMER HARTMUTH
IPC: F02M37/08
Filed: 1981-10-15
Abstract: A unit is proposed for feeding fuel from a storage tank to an internal combustion engine. The feed unit comprises a feed pump and an electric motor for driving the latter which is enclosed in a housing and through which the fuel flows. The conventional fuels with an electrical conductivity in the picosiemen range do not present problems in such an electric motor. However, the alcoholic fuels (M15, M100, E100 etc.) which have recently acquired greater prominence have an electrical conductivity in the microsiemen range and consequently behave like an electrolyte, with the result that the current-carrying bare conductors on the positive side of the motor load-current circuit are attacked and eroded. Fitting a component on the positive side of the motor load-current circuit which is made of a material which is more base than the materials of the current-carrying bare conductors on the positive side of the motor load-current circuit largely protects said conductors against electrolysis. <IMAGE>

Title: Bogie mounting with false pivot in toy and model railway vehicles
Inventor: ZOBERBIER JUERGEN
IPC: A63H19/22
Filed: 1981-11-13
Abstract: The invention relates to a mounting of bogies with false pivot in chassis frames of toy and model railway vehicles. The object of the invention is to achieve low-friction turning and precise pivoting movements as well as undelayed shearing force transmission with low production outlay. In this case, the chassis frame and bogie - as single components - are to be included in the design (using a suitably constructed spring bar which is known per se) in such a way that other function-impairing faults are also avoided. According to the invention, this is achieved in that the chassis frame rests at some points on the bogie on pins moulded on concentrically to the pivot point transversely to the direction of travel so that a low-friction turning movement of the bogie is allowed on the one hand by the two-point bearing thus produced and, on the other hand, the compensation of the differences in the track level is ensured due to a low natural play transversely to the direction of travel and to the inevitable effect as a pivot axis in the direction of travel. The rotary movement of the bogie is allowed by the movable engagement of two bogie projections, constructed in a suitable manner for this purpose, in two guide slots of circular segment shape located concentrically to the pivot point in the direction of travel with functionally suitable dimensions in the bottom of the chassis frame. The virtually loss-free shearing force transmission from the bogie to the chassis frame also takes place via this constructional arrangement. <IMAGE>
